Given: 10x - 4y= 1; X = 2
Prove: 19/4=y

y = 19/4

Step-by-step explanation:

replace x by 2

then 10 × 2 = 20

switch the 20 to the other side and subtract 20 from 1

it will be -19

and -4 will go to the other side as a divide and -

z

-19 / -4 = 19/4

step-by-step explanation:

0

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
